Heat/Cool System for Jacketed Reactor Vessels
Application:
A company producing photographic chemicals for the printing industry needed better temperature control during the heating and cooling of a gelatin-based emulsion in a 480 gallon volume jacketed vessel. A closed-loop hot water system was considered to replace a steam jacketed method.
The customer wanted to get away from the troublesome exposure to hot spots as well as the inefficient transition to cooling. Batch quality suffered resulting in periodic loss of highly expensive product.
Process Conditions:
Temperature Rise per Pass: 3-23°F
Jacket Temperature: 180°F
Product Temperature in 1.1 hour: 120°F
Steam Supply Pressure: 18 PSIG
Solution:
A Pick 6X7-3HCS Packaged Heat/Cool System including a direct steam injection heater was employed to provide hot water across the vessel jacket at a uniform temperature. Hot spots were eliminated and very responsive temperature control was achieved. The transition to the cooling phase of the process was smooth, incorporating a cooling valve for “metered-out” control.
The complete scope of supply was provided including Pick heater, cooling valve, circulating pump, system relief valve with all associated piping, fully installed on a floor support frame.
Features and Benefits:
• Improved Product Quality
• Easy Heat/Cool Transition
• Uniform Jacket Temperatures
• Accurate Temperature Control
• Total System Design
Why Choose Direct Steam Injection for Chemical Processing?
Chemical manufacturers rely on precise temperature control to maintain product quality and process consistency. Pick Heaters' direct steam injection systems provide instantaneous heating, accurate temperature control, and efficient energy transfer for a variety of chemical processes. The technology helps reduce processing time, improve operational efficiency, and support reliable performance in demanding industrial environments.
